So named from Macedonius, an Arian Bishop of Constantinople (342), whose followers denied the Divinity of the Holy Ghost. The Macedonians are usually identified with the Pneumatomachi, or Combators of the Holy Spirit. Unlike their founder the majority of the Macedonians admitted the consubstantiality of the Son. The heresy was combated by Athanasius, Basil, Gregory of Nyssa, Gregory of Nazianzus, and condemned by the first Council of Constantinople (381). Due to internal discord and the severity of the Theodosian Code the sect soon disappeared from history. It was owing to some of the Latin Fathers, in particular Jerome and Augustine, that the term "Macedonianism" became the preferred designation for this heresy in the West.
